21R
The 2-valve SOHC 2.0 L (1972 cc) 21R was produced from 1978 through 1987.
Cylinder bore was 84 mm (3.31 in) and stroke was 89 mm (3.5 in).
Output in 1978, constrained by emissions, was 105 hp (78 kW) at 5200 rpm and 116 ft·lbf (157 N·m) at 3600 rpm. Air injection and California emissions equipment for the 21R-C (1982-1985) dropped power down to 90 hp (67 kW) at 5000 rpm. The air-injected Japanese version, the 21R-U, produced 105 hp (78 kW) at 5200 rpm and 120 ft·lbf (162 N·m) at 3600 rpm but dropped to 101 hp (75 kW) at 5400 rpm and 114 ft·lbf (154 N·m) at 4000 rpm in 1986.
edit:
Thats according to wikipedia
That's the funny and frustrating thing about Wikipedia. Some people think it's the last word and has to be true, but all it takes is one idiot to edit the page and mess it up. I've looked over quite a few toyota pages and found many mistakes. This is one of those pages. As was stated, they weren't offered in the states but were later imported as a cheap and smog legal alternative to the other import option, the 20r and the unavailable 22r. I don't know the exact story but I know it's on this site in more threads than one
I did talk to a couple smog shops, engine shops and importers and got the same exact story from them all. I had one in an 83 4by and had it smogged twice without issue, but you couldn't pay me to run another. The hp numbers are skewed, they're supposed to have 30% less power than a 22r, and having not been able to pull hills or even use 5th on the freeway with 215/75s, I believe it.
What's funny is when people think they have something special. I guess it is special in the same kinda way that bloody slobber covered bird your dog leaves on the floor for you is special
